animal systems
define an animal
a member of the kingdom Animalia, and is typically characterized by a multicellular body, specialized sense organs, voluntary movement, responses to factors in the environment and the ability to acquire and digest food
do sponges have nerves
no
what is bilateral symmetry
symmetry about one axis
Is a mosquito a vector or pathogen
A vector
What separates animals from other organisms, such as fungi?
Because they are the most complex of all organisms.
what is the least complex classification
Porifera
define ectoderm
the germ layer and cell organization in the outside of your body (skin, hair, nails, and nervous system)
Is malaria a vector or a pathogen
A vector
A easy way to identify an animal is if it is motile or not. What does that mean?
To characterize something by it capability of motions.
where do humans fall within a phyla chart?
Chordata
define radial symmetry
symmetry about a rotating axis
pathogen
Why are animals important? and a example.
Any reason on how our cycle works and how we all depend on each other.
what is the only classification that has radial symmetry
Cnidaria
define chordata
bilateral symmetry, with nerves, characterized as a deuterostome, ex humans, fish, dogs.
what is the definition of a pathogen
an agent that causes disease, such as a virus, bacterium, protozoan, or parasite
Why is competition important in the animal kingdom? And an example.
Anything about how we keep each other in shape by controlling each others populations.
name the full 3 characteristics of an earth worm (nerves?, radial or bilateral symmetry?, protostome or deuterostomes?)
they have nerves, bilateral symmetry, and protostomes.
define deuterosotme
Deuterostomia is a subtaxon of the Bilateria branch of the subkingdom Eumetazoa, within Animalia, and are distinguished from protostomes by their deuterostomic embryonic development
what is a vector
an organism, often an arthropod, that carries a pathogen to its host
